Answers to common questions from Los Gatos homeowners.
Barcci Builders publishes $175,000–$450,000+ as an initial planning range for this service in Los Gatos. It is not a market average or quote. The proposal depends on ADU pathway, site constraints, utilities, access, fire requirements, engineering, finishes, and permits.
A reliable schedule requires a defined scope and an agency review path. Design, engineering, corrections, procurement, inspections, site conditions, and approved changes can affect duration. Barcci separates its planning assumptions from timelines controlled by outside agencies.
For ADU law, use the current California HCD handbook and confirm the property-specific pathway with the local agency. Permit scope depends on the work and property, so preliminary guidance should not replace confirmation from the reviewing agency. Barcci coordinates submittals and plan-check responses when included in scope.
The project proposal and signed agreement identify the included work, pricing method, selections, allowances if any, exclusions, schedule assumptions, payment terms, and written change-order process. The published $175,000–$450,000+ range does not replace those documents.
